"When Steve started making all the videos, when he was diagnosed five years ago, (it) was for him and Rivers, (but) it just exploded into where he wants to share it with the world. It's an incredible movie," said Tom Capella, Team Gleason board member.

"It's very personal for me. Steve's a dear friend. He's my outlaw. We're not in-laws, we're outlaws and I think Steve's known around the world for his accomplishments on the field, but I think he's going to be known after this for his accomplishments in the field of raising awareness for ALS patients," said William Prieur, Team Gleason supporter.

The world premiere of "Gleason" is Saturday morning. Before it debuted, the screening was sold out for weeks and had a lot of hype surrounding it.
